Not that there's anything new to report from last week, when we saw a prototype Mercedes SLS AMG Roadster at the factory in Affalterbach, but if you're the type that gets giddy over sketches then these are for you.

As sussed out by Auto Bild, these images are said to be German patent office filings for the roadster. Apparently they sneaked out for a stein one evening and were lured back to the home of the Internet. While it's true that black-and-white drawings can only tell you so much about a car, we're thinking we might enjoy having the top down on this even more than we enjoy the coupe. Maybe. Either way, you can see it from every angle and judge for yourself in the gallery of images below.
